To all whom it may concern: 1

Be it known that I, Josnrn 'V; HULL, a citizen of the United States, and a resident of Brooklyn, in the county 0i Kings and State of New York, have invented certain new and useful Improvements in. Closures for Bottles, Jars, and other Receptacles, of which the fol:

lowing'is a specification. i

The invention relates to improvements in :closures for bottles, jars and other receptacles; and it consists in the novel features hereinafter described, and particularly pointed out in the claims.

The invention comprisesan integral cap to be ap-- blank from which the cap is formed isslitted to create tongues at several points in the beading, these tongues extending, in the finished cap, below the packing-ring and vertically along the sides of the beading to the top of said ring, and said tongues being of sufii'cient extent to permit projecting portions thereof to extend downwardiy below the packing ring and beading and constitute ringer pieces for facilitating the unsealing or loosening of the packing ring from its firm contact with the bottle-neck. When it is desired to unseal the bottle and remove the cap the tongues will be pulled outwardly in a direction from the bottle-neck and packing and thereby crcatc spacesat the outer side of the heading on the cap into which the elastic packing may expand and thus release a part of its pressure from the bottle-neck, the cap in this way being sufiiciently loosened to permit of its convenient removal.

The invention will be fully understood from the detailed description hereinafter presented, reference being had to theaccompanying drawings, in which:

Figure l is a top view of the cap prior to the formation thereon oi the heading which holds the packing; Fig. 2 is an edge view of same; Fig. 3 is a bottom view of same after the projecting flange surrounding the dome of the cap has been fashioned into'thc beading to roccivc the packing ring, the latter being also shown in position; Fig. 4 is an edge view of same, partly in section on the dotted line 4-4 of Fig. 3; Fig. 5 is a dctachcd pcrspcctive view of a portion of the cap showing the relation of-thc tongue to the other portions of the beading after the cap is ready to be applied upon a bottle-neck; Fig. 6 is an enlarged vertical transverse section through a portion of the cap with the parts shown in their initial condition preparatory to-being placed upon the neck of a bottle, the heading on the cap being shown as merely holding the backing-ring I and as not having been reduced, by vertical pressure, to its final form for'effecting, through the packing, the" sealing of the bottle; Fig. 71s a like yiewof same show ing'thc relation of the parts-after the cap has been applied upon a bottle-neck and the heading has been reducedbyvertical pressure to its final form and the pack-ingcompressed and at its inner peripheral portions squeezed laterally against the bottle neck, a portion of the squeezed-out part, of the packing being partly below and partlyabove a shoulder'formed on said neck, and, Fig. 8 is a top view of a modified form of cap, the

and that illustratedin Rig; Breferring merely to the formation-of the slits creating the tongues.

In the; drawings, 10 designates the cap, 11 the annular beading formed thereon, 12 the packing-ring held within saidbeading, and 13 the releasing-tongues. The initial condition and relation of the parts of the cap as the latter is prepared ready to be applied over the mouth of a bottle or the like is shown in Fig. 6, while Fig 7 illustrates the cap in its final condition.

' sealing the bottle. v V The cap is formed from an'integral blank of sheet .metal which at first is pressed into the shape shown in Figs. 1 and 2, the dome 14 being thereby formed and provided at its lower edges with the horizontal encompassing flange 15, which is slit, as at 16, to divide thesaid flange. into segments 17 and intermediate releasingiongucs 13. The outer ends of the tongues 13 extend outwardly beyond the outer edges of the difference-between .the construction shown in Fig. 1

segments 17 to finally form finger'pieces, and the 'flange 15 is finally iormed into the finished beading shown in Fig. 7 the said slits shall extend along the bottomand vertical sides of said beading and preferably not across the top of same.

After the formationshown in Fig. 1 has been prepared the outer portions of the segments 17-along a edge of the flange 15 are bent downwardly, and the -1ernaining portions of the segments are left horizonta t circular line about two-thirds inwardly from the outer ing ring ].2 is introducedto position within the walls I cap. In the-initial condition of the beading 1], shown in Fig. 6, the lower inner edges of the then bent segments 17 do not extend inwardly to the inner vertical edges of the packing 12 but lie outwardly beyond the same and beyond the vertical plane of the sides of the dome 14. The segments 17 are first bent below the packing 12 and then the tongues 13 are folded in- ,wardly, the folded portions of said tongues not contacting with the packing but with the lowersurface 0f the flanges formed by bending the. segments against the lower surface of the packing. The folding below the packingof the outer portions of the segments 17 results in the adjaccnt'ends of said segments approaching each other, as shown in Fig. 5, this being due to were in their flat shape shown in Fig. v1, and thercfore when the outer portions of the segments l7 are ther treatment for effecting the sealing. After the closure has been placed upon the bottle folded below the 'packing'12 before the tongues 13 are thus folded, said tongues will lap upon the outer The parts, having been shaped and assembled, as shown in Fig. 6, the closure is ready to be applied to a bottle or'the like, numbered l8, and receive furthe sealing will be effected by pressure applied vertically against the lower horizontal surfaces of the beading 1.1 and tongues 13,.to compress the packing 12, while at the. same time the top and sides of the dome 14 and'the top and outer sides of the heading ll are held within a closely fitting socket in the capping machine and prevented from expanding or becoming distorted C outwardly, the effect of the vertical pressure against the lower horizontal surfaces of the heading and tongues being that the metal will be pressed upwardly and the packing compressed and said metal caused to move inwardly during the shortening in the height of the beading until it assumes the position shown in Fig. 7-, in which it may be seen that the inner vcrticaledgesof the bottom of the heading and-the tongues 13 have been forced inwardly until they are about in line with the vertical plane of the sides of the dome l4 and that the beading has been given a lower surface orbottom about equal in extent to its top. The vertical pressure applied for sealing the cap upon the bottle thus reduces the vertical height of the beading ll and completes the formation of the beading by causing the metal which is provided to forr'n the bottom thereof 'tO ll'lOVC .iniv'ardly below the packing. 'lhe dome of the cap and the top and vertical sides of the heading being held within a closely fitting socket during the compression of the packing, the metal at the lower portion of the beading cannot move outwardly and is consequently compelled to move inwardly to complete the formation of the beading l]. The vertical reduction in the size ofthe bonding ll results in the packing 12 being comprvsscd and having its inner peripheral portion squccvled outwardly against the neck of the bottle 18 and passing partly abovcand partly'bclow the shoulder 19 on the .ends and pulled outwardly to bend the tongues from below the beading l l. and away from the vertical sides thereof, this having the effect of enabling the elastic packing to expand outwardly through the spaces previously covered by the tongues, whereby said packing is caused to release itsfirm sealing contact with the bottle '7 .neck and permit of the removal of the cap without undue exertion or the use of special tools.

In Fig. 8 I illustrate a modification of the formation shown in Fig. 1 in that in cutting the slits 16 I remove I a portion oi the end edges of the segments 17 so as to leave angular spaces at each side of cachtonguc 13 and form projecting lips 20 which in the formation of the segments 17 into the heading 11 pass below the packing and are engaged by the folded-under portion of the tongues, while along the vertical sides of the heading 11 the creation of the double thickness of metal indicated in Figs. 4, 5 and 6 is avoided, since due to thocutting away of the end edges of the segments, the parts 21 thereof will, along the vertical sides of the heading, match the side edges of the tongues 13 andtthus leave thc= bcading with a uniform outer vertical surface but slit from its lower to its upper edge. The tongues shown in Fig. 8 are the same construction, purpose and operation as those shown in Figs. 1, G and 7. The slits 1,6 may be variously formed and l presentFig. 8 to indicate that said slits may be so shaped as to enable the tongues to lie inbetwccn the adjacent end edges of the segments 17 in the completed beading ll.

What claim as my invention and desire to secure by Letters-Patent, is

1. A closure comprising a cap having at its lower edges ml integral outwardly;projecting annular bending com posed of segments and intermediate tongues, and a pack lug-ring within the recess formed by said beading, snid tongues being free to be pulled outwardly from the bead- Ina: when it is desired to remove the closure; substantially as set forth.
